Convert VOB to mkv

Posted on 2009-12-17
Last Modified: 2013-11-13
I have a DVD rip(standard DVD) that is in VOB format and I want to convert it to MKV.
I can use handbrake to import the dvd and convert but the file size is much less.
The original file lets say is 4GB the converted file is like 2G which means some compression or something is going on.  I used all the highest settings with handbrake but the same issue.
My assumption is that the output to mkv should be close in size to the DVD.  Any help?
I want the output to be mkv with the same video quality, lossless if I am using my terminology correctly.

     the vob is another name for the mpeg2
     While in Vob state undecrypted it uses AC3-5.1 something in that area of the audio  and a video scale of 720 X 640
    did you check the video scale in the mkv?

    when decrypted to mpeg2 it will be smaller than the original Vob because the audio format is converted
    Converting the mpeg2 to MKV should not effect the quality or the video scale the only reason the size may change is probably the audio codec is altered again
    To test codec properties  video scale and audio used
    run Gspot and drop your Vob on and then compare it to the MKV to see if the video scale or audio is different
